Description
Technical field
This utility model relates to field of liquid crystal display, particularly relates to a kind of liquid crystal display module containing circular polarizing disk.
Background technology
The full name polarized light piece of polaroid, the imaging of liquid crystal display must rely on polarized light, all of liquid crystal to have before and after's two panels polarized light piece to be close to liquid-crystalline glasses, form the LCD panel of total honest and kind about 1mm.If having lacked any polaroid, LCD panel all can not show image.Polaroid is one of liquid crystal display important materials, be by polyvinyl alcohol (PVA) stretched film and cellulose acetate membrane (TAC) through being repeatedly combined, stretching, a kind of composite of making of the technique such as coating, liquid crystal display high brightness, high contrast features can be realized.Polaroid accounts for about the 10% of TFT-LCD panel cost.Summarize the multiple technologies such as macromolecular material, microelectronics, photoelectron, thin film, high purity chemical and computer control due to its production technology, therefore, polaroid has higher technology content.
Display screen with artifical resistance touch is the touch interface of by far the most commonly used mobile communication equipment.Reason will be apparent from: low cost, low energy consumption, laminate structure, narrow edge, be applicable to small size show, finger or pen-based input, and have numerous suppliers.But its image is the most clearly, particularly under external sunlight or high light direct projection, the visuality of display image is poor.In recent years, liquid crystal display (LCD, Liquid Crystal Display) such as mobile phone display screen, notebook computer, computer display, LCD TV, panel computer and other video player LCDs etc., day by day become main flow in flat pannel display market.Liquid crystal display screen is the core of liquid crystal display; liquid crystal display screen panel front-back is respectively arranged with one layer of polaroid; the most front polaroid is exposed to outside; processing technology and material characteristics due to polaroid; general the most wear-resisting; meet the easy degumming of dampness, degeneration was lost efficacy, it is impossible to be directly used in outdoor display, it is generally required to increase a block protection eyeglass or touch screen (hereafter referred to collectively as cover plate) before outdoor liquid crystal display screen.If cover plate and liquid crystal display bonding, centre will be produced an air layer with shape of the mouth as one speaks glue.Along with image quality, visual effect requirement are improved constantly by user, the luminance factor of air layer is higher, can produce the strongest dazzle under stronger ambient light, causes not seeing the picture material that liquid crystal display screen shows.
Utility model content
For deficiency of the prior art, the technical problems to be solved in the utility model there are provided a kind of liquid crystal display module containing circular polarizing disk.
For solving above-mentioned technical problem, this utility model is realized by below scheme: a kind of liquid crystal display module containing circular polarizing disk, and this liquid crystal display module includes that touch screen module, LCD module, described touch screen module are placed in LCD module top；
Described touch screen module includes upper polarizer, upper phase shift films, lower phase shift films, described upper polarizer is fitted with upper phase shift films, it is coated with ITO coating at the another side of upper phase shift films, it is provided with the first air gap between described lower phase shift films and upper phase shift films, described lower phase shift films is coated with lower ITO coating towards the one side of the first air gap, and the surface configuration at lower ITO coating has array spaced points；
Middle polaroid that described LCD module includes fitting together, LCD backlight layer, lower inclined sheet, the outer face of described middle polaroid is towards lower phase shift films.
Further, it is provided with the second air-gap between described touch screen module and LCD module.
Further, the thickness of described touch screen module is between 0.3 ~ 0.5mm.
Further, described upper ITO coating, lower ITO coating thickness between 20 ~ 30nm.
Further, described middle polaroid is circular polarizing disk.
Further, the thickness of described middle polaroid is 0.125mm.
Relative to prior art, the beneficial effects of the utility model are: liquid crystal display module of the present utility model had both maintained traditional liquid crystal display screen low cost, the feature of low energy consumption, the problem simultaneously efficiently solving visual angle and contrast.
Accompanying drawing explanation
Fig. 1 is this utility model liquid crystal display module structural representation.
Fig. 2 is this utility model liquid crystal display module luminous reflectance schematic diagram.
Labelling in accompanying drawing: touch screen module 1, LCD module 2, upper polarizer 11, upper phase shift films 12, upper ITO coating the 13, first air gap 14, spaced points 15, lower ITO coating 16, lower phase shift films the 17, second air-gap 21, middle polaroid 22, LCD backlight layer 23, lower inclined sheet 24.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.
Refer to accompanying drawing 1, a kind of liquid crystal display module containing circular polarizing disk of the present utility model, this liquid crystal display module includes that touch screen module 1, LCD module 2, described touch screen module are placed in LCD module top；Described touch screen module includes upper polarizer 11, upper phase shift films 12, lower phase shift films 17, described upper polarizer 11 is fitted with upper phase shift films 12, another side at upper phase shift films 12 is coated with ITO coating 13, the first air gap 14 it is provided with between described lower phase shift films 17 and upper phase shift films 12, described lower phase shift films 17 is coated with lower ITO coating 16 towards the one side of the first air gap 14, and the surface configuration at lower ITO coating 16 has array spaced points 15；Middle polaroid 22 that described LCD module includes fitting together, LCD backlight layer 23, lower inclined sheet 24, the outer face of described middle polaroid 22 is towards lower phase shift films 17.The second air-gap 21 it is provided with between described touch screen module and LCD module, the thickness of described touch screen module is between 0.3 ~ 0.5mm, described upper ITO coating 13, lower ITO coating 16 thickness between 20 ~ 30nm, described middle polaroid 22 is circular polarizing disk, and the thickness of described middle polaroid 22 is 0.125mm.
As shown in Figure 2, use the phase shift films on two lTO coating, and do not use isotropic membrane, do not use isotropic membrane that touch screen can be made to become thinner (gross thickness is 0.5 mm), and reduce cost, and reflectance is had not significant impact, this is because the most still there is ITO layer thick for 30 nm.As film one glass structure, the total reflectivity under best-case is about 1%.Circular polarizing disk film one film touch screen and LCD optics are bonded together and creates the reflectance of minimum.Additionally
Bonding add intensity and reduce integral thickness.
The foregoing is only preferred implementation of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in scope of patent protection of the present utility model.
